The present invention relates to a slope reinforcing device, and more particularly, to a slope reinforcing material having an improved structure for stabilization of a slope, and an economical and environmentally friendly slope reinforcing device and a method thereof.

In general, slopes installed in conjunction with large-scale land construction, roads, railways, etc. are largely susceptible to natural disasters. Therefore, the slope reinforcement method has been actively progressed to secure the stability of the slope.

The slope reinforcement method has been used differently depending on the characteristics of the slope. For example, when it is difficult to artificially increase the shear force such as weathering zones or cladding layers, or when permanent stability is required as a slope around important facilities, a method of lowering the slope angle of the slope was used. And, the rock condition is good, but the shear force of the discontinuous surface problem or the development of the discontinuous surface, such as plate joint and columnar joint is relatively regular where a rock bolt or a method using a cable was used. In addition, retaining walls were used where the height of the slope was relatively low and where vegetation or masonry was needed at the top, or where the slope of the slope was urgently adjusted to reduce the amount of rock excavation. In addition, drainage principles were used, or wire mesh, vegetation, or mason's methods were used.

However, in the slopes, the base is not very clear and is very heterogeneous, and the weathering, stratification and cracks are irregular and variously distributed. Therefore, there is a need for a method that is economical and applicable to both soil and rock slopes while increasing slope stability. In recent years, the natural environment problem has emerged as an important issue with respect to slopes installed along roads or railway construction, and thus, an environmentally friendly slope reinforcement method is required.

The following is a brief description of the Soil nailing method that is widely used for the stabilization of the slope.

Soil nailing method is a method of installing reinforcement materials (nails, etc.) on the base to form reinforcement base that improves the strength of the base, thereby increasing the shear and tensile strength of the ground and restraining displacement and preventing ground loosening. . This is a kind of reinforcement earthwork using reinforcing bars and directly reinforces the strength of the slope itself. In other words, the basic design concept of the Soil Nailing Method is to maintain stability against any inclined surface that can be assumed by the reinforcement soil wall by acting as a unitary retaining wall.

Looking at the construction sequence of the slope reinforcement method using the Soil Nailing, first, the slope to be installed is excavated, and the foreign matter on the slope is removed. At this time, the excavation equipment should thoroughly investigate the facilities of underground buried grounds, buildings, etc., and minimize the ground disturbance by using the ones that meet the design conditions. In addition, the first shotcrete may be performed to prevent the loosening of the slope that may occur at this time. After this, the nail is formed on the slope, the drilling angle is preferably inclined downward 15 ° ~ 30 °. Then, a nail is installed in the nail ball and grouting is performed inside the nail ball. At this time, the nail ball is not collapsed, and the nail is placed in the center of the nail ball. In addition, it is preferable to mix grout in accordance with site soil conditions according to the soil properties of the ground. After that, wire mesh, etc., which is a protection net to prevent rockfall, is installed on the entire slope, and finally, second shotcrete is performed on the entire slope to finish slope reinforcement.

However, the conventional soil nailing method has the following problems.

Conventional Soil nailing method has the effect of increasing the stability of the slope by performing shotcrete over the entire slope, there was a problem that it is not environmentally friendly. In other words, even if the planting of the shotcrete is completed by using a plant such as grass on the slope, there is a problem that the planted plant cannot grow due to the blocking of the capillary phenomenon by the shotcrete.

Recently, in order to solve the problems of the conventional soil nailing method, a reinforcement method that is environmentally friendly and can stabilize a slope is used.

According to the invention disclosed in Korean Patent Laid-Open No. 2004-0036435, the slope is stabilized by using a high elastic high tension crimping network without placing shotcrete. 1 shows a slope reinforcing device according to the prior art. Hereinafter, referring to FIG. 1, the slope reinforcing device according to the related art will be briefly described as follows.

Slope reinforcement device according to the prior art is composed of a slope reinforcement (1) for strengthening the ground strength and the wire mesh (2) for the collapse of the ground and falling rocks. In addition, the slope reinforcement (1) is specifically composed of the main reinforcement (3) (hereinafter referred to as "reinforcing member"), the pressure plate (4) and the fastener (5).

The reinforcing member 3 is the same as the nail or rock bolt (rock blot) in the above-described soil nailing method. In other words, when installed as a high-strength deformed steel reinforcement is fixed to a certain portion protruding out of the slope is coupled to the fixture. The reinforcing member (3) is installed on the slope by a predetermined number of times through the stable analysis of the slope, the main purpose is to improve the strength of the base. As will be described later, the reinforcing member 3 also serves to support the wire mesh 2.

The pressure plate (4) is installed on the upper surface of the reinforcing member hole 31, and in close contact with the slope serves to assist in fixing the reinforcing member (3) by transmitting the pressing force of the fixture (5) to the reinforcing member (3) Do it. Similarly, the pressure plate 4 also serves to press the wire mesh 2 installed on the entire slope.

The fixture 5 is installed on the top of the pressure plate 4, the pressure plate 4 is pressed to the slope and serves to fix the reinforcing member (3). In addition, it serves to support the wire mesh material (2) together with the pressure plate (4) and the reinforcing member (3).

The wire netting material 2 is installed in a roll shape on the entire slope, and is connected to the reinforcing member 3 by being stretched vertically and horizontally. And, depending on the width of the slope may be installed using a connecting ring. The wire mesh 2 serves to increase the shear resistance of the slope by applying the preceding compressive stress to the slope in combination with the reinforcing member (3). In addition, the wire mesh (2) serves to reduce the relaxation of the slope rock by pressing the slope, and to prevent rockfall and rock aggregates fall.

On the other hand, in order to perform the role of the wire mesh as described above, the wire mesh 2 is subjected to a processing process to have a high tensile and elastic force. The process of processing the wire mesh 2 is as follows. First, the alloy steel or spring steel is loosened and then stranded. After the heat treatment again to reinforce the restoring force on the wire mesh, and to the galvanized to prevent corrosion to complete the wire mesh (2).

However, the prior art had the following problems.

First, the gap between the upper surface and the pressure plate of the reinforcing member hole in which the reinforcing member is installed in the conventional slope reinforcement may occur due to weathering and erosion. As a result, the pressure plate is unable to maintain a state in contact with the slope, and as a result, the fixture has a problem in that it is not possible to continuously fix the pressure plate in a compressed state on the slope.

Second, the high-strength high-elasticity wire mesh according to the prior art is installed as a narrow mesh over the entire slope, and the processing of the wire mesh requires a considerable cost, so there was an economic burden on the production of the wire mesh.

Third, the high-elastic high-tensile wire mesh according to the prior art is installed on the slope in the form of a roll, there was a problem that the partial repair is not easy when the wire mesh and the slope partially broken. In addition, applying a tensile force directly to the wire mesh has a problem that is substantially difficult because of the special material of the wire mesh. That is, when tensioning high elasticity of the wire mesh and connected to the slope reinforcement, there was an inconvenience that the wire mesh can not be stretched in a uniform direction due to the high tension of the wire mesh.

Fourth, in the slope reinforcement device according to the prior art due to the erosion between the pressure plate and the surface of the reinforcing member hole is not able to compress the wire mesh material on the slope, the wire mesh material installed on the entire slope is floating on the slope, There was a problem that the resilience is weakened.
